They are not GF certified but take immense precautions to prevent cross-contamination. My non-GF friend lucked out because they only had one mushroom galette left but it had been touched with a non-gluten glove. They had it in a marked bag off to the side.
Amazing, amazing GF pastries, salted chocolate chunk cookies, galettes, tarts, cakes, etc. And the GF vegan cinnamon rolls are incredibly good, by far the best GF ones I’ve had. I’ve had them fresh from the bakery & bought a refrigerated bake at home 6pack & both were great. For Valentines I preordered GF passion fruit & sea salt caramel tarts, & jelly fruit bites. All were good, their tart crust is seriously close to the real thing, & I wish I’d ordered 5 of the passion fruit ones!
